1. A golf club head, comprising:
a sole positioned at a bottom portion of the golf club head;
a crown positioned at a top portion of the golf club head;
a skirt positioned around a periphery between the sole and crown;
a forward portion and a rearward portion; and
a face positioned at the forward portion and including a striking surface, the striking surface having a golf club head origin positioned at a geometric center of the striking surface, the golf club head origin including:
an origin x-axis tangential to the face and generally parallel to a ground plane when the golf club head is ideally positioned,
an origin y-axis generally perpendicular to the origin x-axis and generally parallel to the ground plane when the golf club head is ideally positioned, and
an origin z-axis perpendicular to both the origin x-axis and origin y-axis; and
at least one mass element having a mass of at least 5 g and secured to or integrally formed in the golf club head, the at least one mass element located:
rearward of a golf club head center of gravity, and
at least 90 mm from the golf club head origin;
wherein:
the rearward portion is configured to at least partially receive and retain a weight below the crown;
the origin x-axis extends in a positive direction from the golf club head origin toward a heel portion of the golf club head, the origin y-axis extends in a positive direction from the golf club head origin towards the rearward portion of the golf club head, and the origin z-axis extends in a positive direction from the golf club head origin towards the crown of the golf club head;
a maximum club head depth of the golf club head is between 115 mm and 130 mm, a maximum club head height is between 55 mm and 75 mm, a maximum club head width is between 110 mm and 130 mm, and a volume of the golf club head is between 420 cm3 and 480 cm3;
the golf club head has a club head mass between 190 grams and 210 grams;
a ratio of a moment of inertia about a golf club head center of gravity x-axis generally parallel to the origin x-axis to a moment of inertia about a golf club head center of gravity z-axis generally parallel to the origin z-axis is from 0.67 to 0.90;
the moment of inertia about the golf club head center of gravity x-axis is less than the moment of inertia about the golf club head center of gravity z-axis;
the moment of inertia about the golf club head center of gravity z-axis is 495-702 kg·mm2;
the golf club head center of gravity has a z-axis coordinate between −8 mm and 0 mm; and
the golf club head center of gravity has a y-axis coordinate no less than 33 mm as measured relative to the golf club head origin.
